Question

A 1.40-kg block of wood sits at the edge of a table, 0.760 m above the floor. A 1.00×10−2-kg bullet moving horizontally with a speed of 745 m/s embeds itself within the block

What horizontal distance does the block cover before hitting the ground?

Answer #1

A 1.05-kg block of wood sits at the edge of a table, 0.780 m
above the floor. A 1.05×10−2-kg bullet moving horizontally with a
speed of 750 m/s embeds itself within the block. What horizontal
distance does the block cover before hitting the ground?

A 1.05-kg block of wood sits at
the edge of a table, 0.770m above the floor. A 1.05

A 2.8 kg block of wood sits on a frictionless table. A 3.0 g
bullet, fired horizontally at a speed of 400 m/s , goes completely
through the block, emerging at a speed of 220 m/s .
What is the speed of the block immediately after the bullet
exits?

A 15 g bullet is fired at 610 m/s into a 4.7 kg block that sits
at the edge of a 75 cm-high table. The bullet embeds itself in the
block and carries it off the table.
How far from the point directly below the table's edge does the
block land?
Express your answer with the appropriate units.

A 15 g bullet is fired at 610 m/s into a 4 kg wood block that is
at rest on the edge of 75 cm high table. The bullet embeds itself
in the block and carries it off the table.
a. What are forces acting on the block+bullet? (Or draw a free
body diagram of forces acting on the block+bullet.)
b. What was the momentum of the bullet before it hit the
block?
c. Write down the statement of conservation...

A)A 2.9 kg block of wood sits on a table. A 0.0035 kg bullet,
fired horizontally at a speed of 440 m/s, goes completely through
the block, emerging at a speed of 140 m/s.What is the speed of the
block immediately after the bullet exits?
Answer in m/s
B)A small, 0.43 kg cart is moving at 1.4 m/s on an air track
when it collides with a larger, 5 kg cart at rest. After the
collision, the small cart recoils...

A
12-g bullet moving horizontally with speed of 350 m/s strikes and
remains in a 4.0-kg block initially at rest on the edge of a table.
The block, which is initially 80 cm above the floor, strikes the
floor a horizontal distance from the base of table. What is the
horizontal distance on the floor?

A 5.50 g bullet is fired horizontally into a 1.40 kg wooden
block resting on a horizontal surface. The coefficient of kinetic
friction between block and surface is 0.200. The bullet remains
embedded in the block, which is observed to slide 0.230 m along the
surface before stopping. Find the initial speed of the bullet.

A bullet of mass m = 2.40×10-2 kg is fired along an incline and
embeds itself quickly into a block of wood of mass M = 1.35 kg. The
block and bullet then slide up the incline, assumed frictionless,
and rise to a height H = 1.35 m before stopping. Calculate the
speed of the bullet just before it hits the wood.

Two 500 g blocks of wood are 2.0 m apart on a frictionless
table. A 9.0 g bullet is fired at 430 m/s toward the blocks. It
passes all the way through the first block, then embeds itself in
the second block. The speed of the first block immediately
afterward is 5.8 m/s .
What is the speed of the second block after the bullet
stops?
